Why This Stablecoin Tax Could Shift Crypto Activity

France is proposing to extend its 31.4% capital gains tax to include swaps into EU-regulated stablecoins starting in January 2027. The change would treat exchanging bitcoin or other cryptocurrencies for MiCA-compliant stablecoins as a taxable event, which is not currently the case.

Chainalysis warns the measure could drive traders toward less transparent offshore stablecoins. The firm's France CEO Francois Volpoet argues authorities can more easily track regulated stablecoin transactions than DeFi trades or self-custody movements, potentially pushing investors toward channels that are harder to monitor. Volpoet specifically frames the concern as a choice between a higher tax rate on a more traceable base or a lower rate on one that effectively disappears into the shadows.

The proposal is part of France's 2027 budget under debate in the National Assembly, with a vote on the revenue section scheduled for October 20. Additional measures would require French taxpayers to disclose self-hosted crypto wallets holding at least €100,000, with fines up to $11,600 for non-compliance. The plan would also extend the exit tax to crypto holdings worth roughly $900,000 and allow losses to be carried forward for up to 10 years, bringing crypto taxation into line with rules already applied to traditional asset holders.

If passed, the tax could significantly increase the cost of moving between cryptocurrencies and stablecoins, potentially reducing liquidity in regulated options while driving volume toward unregulated alternatives. The wallet disclosure requirement also expands the regulatory net to individual crypto holders, marking a significant shift in France's approach to crypto taxation. Readers should understand that even if the law does not yet exist, the direction of policy is clear: holding and moving stablecoins may become substantially more expensive.
